.Application mea February 1, 1911. serial No. 605,927.

An important obj ectof my invention is to provide a furnace ofthe above mentioned character, which-is economical and thorough in operation. p f

Other objects and advantages of this in vention will be apparent during thecourse of the following description.

In the accompanying drawings forming a part of this specification and in which like numerals are employed Ato designate like parts throughout the same, Figure 1 is a longitudinal vertical sectional view taken through the'furn'ace, Fig.V 2 is a* transverse vertical sectional view taken on line 2-'2 of Fig. 1, and, Fig. 3 is a horizontal sectional view taken on line 3-3 of Fig. 2.

In the drawings wherein is illustrated a preferred embodiment of my invention, the numeral 1 designates an inner or heating chamber, which is shown as being in the form of a parallelepiped. I do not wish to restrict myself to any particular shape of this heating chamber, as the same may be formed cylindrical or otherwise. The heating chamber 1 is disposed centrally within and is entirely surrounded by an outer chamber or casing 2. The chambers 1 and l 2 may be formed of fire brick or other suitable heat resisting material.

Below the bottom wall of the heating chamber 1 are horizontal lines or ports 3, which establish communication between spaces 4 and 5, disposed between the side walls of said chambers. Spaces 6 and 7 are provided, which are disposed between the end walls of the chambers 1 and 2 and have free communication with the spaces 4 and 5.

. The end spaces 6 and 7 and the side space 5 have communication with a top space 8. The top space 8 is disposed between the top walls of the chambers 1 and 2 and discharges into a stack 9. The upper end of the side space 4 is closed by an arch 10,

which connects the chambers 11and2, as shownlin Fig. 2.

1 The side and end walls of the `outer-cham` ber 2 `may preferably be `provided with air spaces 11. The top wall ofthe'outer` cham- 60 ber 'is provided with a curved space or opening which may preferably be l'illed with asbestos 12. The upper surface of the top wall ofthe outer chamber 2, ispreferably covered with sand 13,-as shown. Y

Material is fed into the inner or heating chamberl through ,openings l14, which are preferably vertically `disposed and extend through the top walls of the chambers land 2. These openings also pass through cylin-` '70` ldrical sections of material 15, which serve toconnect the top walls o-f said chambers. rlhe openings 14 also serve to allow the gases formed in the heating chamberl -to escape. The material is removed fromthe heating 7'5` chamber 1 through `an opening 16, `which is closed. by a suitable door `(not shown).

The side walls of the heating chamber 1 `are `provided with pairs of openings or win-p.

dows 17, the windows in each pair being in horizontal alinement. Each of the windows 17 is closed by a pane of fused quartz or other suitable translucent material 18. Disposed between the windows 17 are vertical columns 19, which serve to divide the side spaces 4 and 5 into two compartments, as shown. The side walls of the outer chamber 2 are provided with openings 2O formed therethrough, which are in alinement with the openings or windows 17, as shown. Disposed near and below each of the translucent panes 18, is a horizontal baffle plate 21, having connection with the walls of the chambers 1 and 2. Disposed near the upper end of each of the panes 18 is a pair of 95 spaced baffle plates 22, which are also connected with the side walls of the chambers 1 and 2.

The side walls of the outer chamber 2 are provided with openings 23, to receive suitable burners of the hydrocarbon injector type. Each of the burners comprises a lower air supply pipe 25a and an upper gas supply pipe 25, having its inner end extending into the pipe 25a, as shown. These 105 burners direct iames which impinge against the translucent panes 18.

The panes 18 are formed of material which is not readily affected by the action of heat and are made thin so that the heat from the ame which impinges against them may readily radiate into the chamber 1.

In the use of my furnace, material is fed into the heating chamber 1 through the openings 14 until this chamber is completely filled. The iames from the burners are then directed tov impinge against the translucent panes 18. The products of combustion from Vthese flames are discharged into the spaces surrounding the heating chamber 1, and after passing about said heating chamber on all six sides, said products are introduced into the stack 9. It will thus Abe seen that the material within the chamber 1 is heated by the products of combustion passing about said chamber and also by the heat radiating from the translucent panes 18.

I wish it understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same and that certain changes in the shape, size and arrangement of parts may be resorted to without departing from the spirit of my invention or `the scope of the subjoined claims.

Having thus described my invention, I claim 1. In a furnace of the character described, a heating chamber having its opposing walls provided with horizontally alined openings, fused quartz panes disposed within said openings, and means for holding a suitable burner whichA is adapted t-oprovideY a flame for impinging against said panes.

2. 4A furnace of the character described,`

vthin plates closing such openings and formed of material to withstand the action of heat and to allow of the radiation of the heat through the same to a much greater eX- tent than the walls of theinner shell, a number of openings formed lin the side walls of the outer shell and disposed adjacent lthe openings of the inner shell, and burners of the blowpipe type disposed within the said openings to provide intensely hot flames to impinge against the thin plates which close l iheopenings of the inner shell.

f In testimony whereof I alix my signature in presence of two witnesses.
